Hello I use your kext since long time and you once fixed the MTU 9000 issue when I told you. Many thanks!
Sometimes I had kernel panics when the device was detected at boot, now it's happening more often, I updated the kext to the last version you released.
I haven't the log, I can't find it in /var/log/kernel.log when it panics, but you can see from the picture below, it writes partially panic and freezes like that:

This is a normal successful boot:
